Subject[PATCH v2] dell-wmi: Set correct keycode for Fn + left arrow hotkey
Date
From: Henk <henk.vergonet@gmail.com>

Fn + left arrow hotkey combination is used for enabling/disabling automatic
display brigthness based on integrated ALS sensor. For this purpose there
is standard linux key KEY_BRIGHTNESS_AUTO so use it instead of KEY_UNKNOWN.

Tested on Dell Lattitude E6500.
